IO pins capable of Analog input ?



  • I'm fairly new to duet so I am also new to the documentation but I did a search before posting so apologies if I missed something obvious. The only place where "analog" is mentioned on the hardware documentation talks how there is a separate input for z probe, so I assume that zprobe.in can be linked to ADC, one can also assume all thermistor inputs can be linked to ADC too but nothing about other pins.

    I have a list of pins on a duet2ethernet and while I can see which ones support PWM output I have no clue which ones can support analog input.

    zstop is the first one I'm interested in but general info must exist somewhere so I'd like a pointer to the information if it is available.

    thanks

    The only pins on the Duet WiFi/Ethernet for which the standard firmware supports analog input are the zprobe.in pin and the pins with 'temp' in the name.



  • Thanks. That solves it.
